?-Pyrazine-2,5-dicarboxyl-ato-bis-[chlorido(?-p-cymene)ruthenium(II)] tert-butanol disolvate.

ABSTRACT: A new tert-butanol solvate of [{((i)PrC(6)H(4)Me)RuCl}(2){?-2,5-pyz(COO)(2)}] (pyz = pyrazine) has been crystallized and structurally characterized. The solvate, [Ru(2)(C(10)H(14))(2)(C(6)H(2)N(2)O(4))Cl(2)]·2C(4)H(10)O, contains one half-mol-ecule of the ruthenium(II) complex and one mol-ecule of tert-butanol in the asymmetric unit. The complex mol-ecule lies on an inversion centre with the two chlorides trans. In contrast, the previously reported structure was solvent-free. Similar metric parameters are found between the butanol solvate and the solvent-free form and an inter-molecular O-H?O hydrogen bond exists between ?-pyrazine-2,5-dicarboxyl-ato-bis-[chlorido(?(6)-p-cymene)-ruthenium(II)] and the tert-butanol mol-ecule.

Project description:In the title coordination polymer, [Li(2)(C(6)H(2)N(2)O(2))(H(2)O)(2)](n) the pyrazine-2,5-dicarboxyl-ate dianionic ligand bridges two symmetry-independent Li(+) ions using both its N,O-chelating sites. The carboxyl-ate O atom of one of them also bridges to another Li(+) ion, while the second O atom of this group is bonded to another Li(+) ion. Two symmetry-independent water O atoms participate also in the bridging system, which gives rise to a polymeric three-dimensional framework. Both Li(+) ions show distorted trigonal-bipyramidal LiNO(4) coordination geometries, with the N atom in an axial site in both cases. The packing is consolidated by O-H?O hydrogen bonds, which occur between water mol-ecules as donors and carboxyl-ate O atoms as acceptors.

Crystal structure of [3-amino-2-(phenyl-diazenyl)-pyridine]chlorido-(η(6)-p-cymene)-ruthenium(II) chloride.

Project description:The title compound, [RuCl(C10H14)(C11H10N4)]Cl is an Ru(II) complex in which an η (6) -p-cymene ligand, two N atoms of 3-amino-2-(phenyl-azo)pyridine and one Cl ion form a piano-stool coordination environment around the metal ion. In the crystal structure, N-H⋯Cl hydrogen bonds play an important role in the formation of the supramolecular zigzag chain along the a-axis direction. Disorder is observed for the isopropyl group with site-occupancy factors refined to 0.78 (5) and 0.22 (5).

Project description:The title compound {(C(3)H(5)N(2))(2)[Pr(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]}(n), has a chain structure featuring a dimeric unit consisting of two Pr(III) atoms within a dodecahedral environment.

The Pr(III) ions are bridged by two ligands along the c axis, forming the dimeric unit, and these are connected by four ligands along the b axis, forming a chain. N-H?O and O-H?O hydrogen bonds are found in the structure.

Project description:In the title compound, [Ru2(C10H14)2Cl2(C16H8N4)](PF6)2·2C3H6O, the binuclear Ru(II) complex dication, [{RuCl(η(6)-cym)}2(μ-tape)](2+), built up by a planar 1,6,7,12-tetra-aza-perylene (tape) bridge, two η(6)-bound cymene (cym) ligands and two chloride ligands, includes an inversion center. The Ru(II) atom shows the typical piano-stool motif for arene coordination. The counter-charge is provided by a hexa-fluorido-phosphate anion and the asymmetric unit is completed by an acetone mol-ecule of crystallization. The components of the structure are connected into a three-dimensional architecture by C-H⋯O/F/Cl inter-actions.

Di-chlorido-(η<sup>6</sup>-<i>p</i>-cymene)[tris-(4-meth-oxy-phen-yl)phosphane]ruthenium(II).

Project description:The title compound, [RuCl2(C10H14)(C21H21O3P)], crystallizes with two complex mol-ecules in the asymmetric unit. The RuII atom has a classical three-legged piano-stool environment being coordinated by a cymene ligand [Ru-centroid = 1.707 (2)/1.704 (2) Å], a tris-(4-meth-oxy-phen-yl)phosphane ligand [Ru-P = 2.3629 (15)/2.3665 (15) Å] and two chloride atoms with the Ru-Cl bonds adopting two distinct values of 2.4068 (16)/2.4167 (16) and 2.4016 (15)/2.4244 (16) Å. The effective cone and solid angles for the phosphane ligands were calculated to be 149.5/150.2° and 25.3/25.6°, respectively. In the crystal, weak C-H⋯Cl/O/π inter-actions are observed. The crystal was refined as a two-component twin.

In the crystal, the complex and solvent mol-ecules are bridged by weak C-H⋯N hydrogen bonds along the c axis. Weak inter-molecular C-H⋯Cl contacts link the complexes in the ab plane, forming a network.

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.
